The Tissot Seastar 1000 merges style and performance without compromising either. With its water resistance up to 30 bar (300 m/1000 ft), screw-down crown and case back, it is a true diving watch. Now combined with the energy of the Powermatic 80 movement, it offers up to 80 hours of power reserve when most of automatic movements boasts around 40 hours. The movement is visible through the exhibition caseback. As expected for a dive watch, it includes a robust unidirectional rotating ceramic bezel. The watch is attached to an interchangeable quick release bracelet that includes a folding clasp with diver extension and push-buttons.
